Heat Safety Tips

Intense heat can quickly become dangerous. Keep an eye on people vulnerable groups including newborns, infants, children and the elderly.

“Heat is one of the leading weather-related killers in the United States, resulting in hundreds of fatalities each year,” the National Weather Service says.

To stay safe in the heat, avoid strenuous outdoor activities, or move them to the cooler morning hours. Stay hydrated, opting for water and sports drinks over sugary beverages. Take shade breaks. Know the signs of heat-related illness.

Never leave a pet or kids alone in a parked car. Temperatures in cars can rise to lethal levels within minutes, even with the windows cracked, according to KidsandCars.org.

Wearing loose, light-colored clothing can also help you stay cool.

Montgomery County declared a hyperthermia alert; here's where to find resources.

Spray parks and public pools are another way to cool down. Pools are open throughout the region, and some have extended hours.
